Facial contouring

Square jaw surgery: long-curved ostectomy including the MVP

GLAM reduces the jaw with a long-curved ostectomy plus cortical shaving that includes the maximal volume point (MVP), so the change reads from both the front and the side without erasing the mandibular angle entirely.

Who it suits

A wide, square jaw on the frontal view
Patients worried about an unnatural, over-shaved jawline

Technique highlights

Reducing the MVP — the widest part of the mandible — makes the change visible from the front
The long-curved cut reduces the risk of a secondary angle
Backed by Strategic Considerations for Effective Sagittal Resection of the Mandible

Surgical steps

Locate the MVP and the nerve canal on CT
Perform a long-curved ostectomy from the angle toward the chin
Add cortical shaving over the MVP to narrow the frontal width

Recovery & aftercare

Sagging is limited by sub-mental muscle plication and fascial suspension in the same operation
LED and radiofrequency programmes help control early swelling

Risks & things to consider

Removing the whole angle does not automatically make the face smaller
The planned cut must keep a safe distance from the nerve canal seen on CT

Frequently asked questions

What is the MVP and why does it matter?

The maximal volume point is the thickest part of the mandible. GLAM states that including it in the resection makes the jawline smaller from both the front and the side while keeping the contour natural.
